A.O. Smith has launched its new high-efficiency modulating variable-fire boilers, which replace the Legend Series, effective April 23. The VF boiler is a totally new design that provides up to 88 percent thermal efficiency while maintaining low NOx emissions that are better for our environment. The vertical tube design allows for a large heat transfer area, which maximizes efficiency, while maintaining the small footprint ideal for retrofit applications and multiple boiler installations.
